Fig. 1 illustrates that the sleeves 38 of which there may betwo are rotatably mounted on a cross shaft 40 and are provided withradial cranks 41 connected to rearwardly projecting links 43 of thebrake operating mechanism 44. Fig. 1 plainly shows that the brakeoperation members 44: have connection with the brakes of the rear wheelsso that when a longitudinal movement in the proper direction is impartedtothe link 83 the brakes will be applied. The

improved equalizer might also be employed.

in connection with four wheel brakes.

In the operation of improved brake equalizer the longitudinal movementof the link 33 in the proper direction results in the turning of one orboth of the cranks and in this manner the brakes are evenly applied toprevent the skidding or sliding of the tires. hen a proper amount ofpressure has been applied to one wheel. by the brake, the braking forceis applied to the other wheel so that the pressure is equalized. Morespecifically the braking force is uniformly distributed to each of thebrake equipped wheels.

Fig. 1 plainly illustrates that the housing 5 of the improved brakeequalizer may be provided with laterally projecting cars having setscrews 51 arranged inthe path of travel of the cranks 31 so as to limitthe movement of the cranks. However movement of the cranks beyond avertical position is seldom necessary as by the differential action ofthe equalizer the uniform application of the brakes brings the vehicleto a gradual and certain stop.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as a preferred example of the same and thatsuch minor changes in arrangement and construction of parts may be madeas will remain within the spirit of the invention and scope of what isclaimed.

Having thus described the invention, what is claimed is:

l. A brake equalizer comprising a casing having a plurality of slots, aspider arranged within the housing and having radial arms positioned insaid slots, pinions mounted on said arms and beveled gears engaged bysaid pinions 2-. A brake equalizer comprising a casing having spacedslots, a spider arranged in the casing and having radial arms positionedin said slots, pinions mounted on said arms, and beveled gears arrangedwithin said casing and engaged by said pinions.

3. A brake equalizer comprising a casing having spaced slots, a spiderarranged in the casing and having radial arms positioned in said slots,pinions mounted on said arms, and beveled gears-arranged within saidcasing and engaged by said pinions, one of said arms of the spiderextended a substantial distance beyond the casing and having meanswhereby the same may be connected directly to an operating member, andcranks having connection with said beveled gears.

4. A brake equalizer comprising a casing consisting of an annulus andside walls connected to the annulus, said annulus being formed withspaced slots, a spider arranged within the annulus and having radialarms, a pinion rotatable 011 each arm, beveled gears engaged by eachpinion, cranks having connection with said beveled gears, one of saidarms of the spider being extended for a substantial distance beyond thecasing and having means whereby the terminal portion of the same may beconnected to an operating member whereby the operating member isconnected directly to the spider for turning the pinions on the beveledgears.

5. A brake equalizer comprising a casing consisting of an annulus andside walls connected to the annulus, said annulus being formed withspaced slots, a spider arranged within the annulus and having radialarms, a pinion rotatable on each arm, beveled gears engaged by eachpinion, cranks having connection with said beveled gears, one of saidarms of the spider being extended for a substantial distance beyond thecasing, having means whereby the terminal portion of the same may beconnected to an operating member whereby the operating member isconnected directly to the spider for turning the pinions on the beveledgears and means to limit the turning of the bev eled gears.

6. A brake equalizer for motor vehicle brakes comprising a casingconsisting of an annulus and a pair of side walls, said annulus beingformed with slots, a spider having radial arms positioned in said slots,pinions mounted on said arms, beveled. gears mounted in said casing andengaged by said pinions, said beveled gears being provided with hubsrotatably extended through said side walls of the casing, shafts securedin said hubs, cranks connected to said shafts, one of said arms of thespider being extended for a substantial distance beyond the casing andhaving its terminal portion formed with means whereby an operatingmember may be connected thereto whereby the operating member isconnected directly to the spider, and adjustable means arranged in thepath of travel of said cranks to limit the turning ofthe same.

In testimony whereof I aflix my signature.

FRED C. BROWN.
